IMPROVEMENT IN STOVES FOR SMOKE-HOUSES.

Specification forming part of Letters Patent No. 145,054, dated December2, 1873; application filed July 9, 1873.

To all whom it may concern:

Be it known that I, ISAAC N. DEARDORFF, of Canal Dover, in the county ofTuscarawas and State of Ohio, have invented an Improved Stove forSmoke-Houses; and I do hereby declare that the following is a full andexact description thereof, reference being had to the accompanyingdrawings making part of this specification Figure 1 being a top view ofthe stove; Fig.

2, a transverse vertical section of the same;

Fig. 3, a longitudinal section thereof, looking downward, in a planeindicated by the line a a, Fig. 2; Fig. 4, a horizontal section thereof,looking upward, in a plane indicated by the line y y, Fig. 2; Fig. 5, adetailed view, showing a modification of parts represented in Fig. 4.

' Like letters designate corresponding parts in all of the figures.

Let A represent the smoke-chamber of the stove; B, the grate, and O theash-chamber, thereof.

f The nature of my invention consists, first, in the construction of thegrate B, with inclined sides a a, and horizontal middle portion I),provided with (preferably oblong) grateapertures c c therein, which arewholly or par tially opened and closed by means of a damper or dampers,d (1, two being shown in the drawin gs, one for the front part or halfof the grate, and the other for the rear part of the grate.

There may be three sections--a middle one in addition to the endsections-or even more than three, if desired; and, instead of sidesliding dampers, as shown in Fig. 4, there may be transverse damperssliding at the ends, as shown in the diagram, Fig. 5.

By means of this grate and damper-regulators, the admission of air tothe fuel and the combustion thereof can be regulated with greatexactness, to suit dry or green fuel, or

any other cause of variation in the combustion and smoke-producingcircumstances.-

vent-apertures being additional to the regular outer apertures g g inthe top of the stove.

The apertures f f are opened and closed, wholly or partially, by meansof a damper or dampers, h h, two being represented in the drawings, oneat one end of the stove, and the other at the other end of the stove,and sliding either endwisc of the stove, as shown, or sidewise.

These dampers have holes it, corresponding in size and position with theholes in the partition-plate D, so that when the damper is moved one waythe apertures in the partitionplate will be uncovered, as shown at theleft hand in Fig. 3, and when the damper is moved in the other directionthe partition-plate aper tures will be covered, as indicated at theright hand in the same figure. These dampers also serve to regulatesomewhat the combustion in the stove below, according to the conditionof the wood, or the draft of the stove.

The apertures f f are represented as being in inclined parts of thepartition-plate D. Any other equivalent construction or arrangement ofparts may be employed.

What I claim as my invention, and desire to secure by Letters Patent,is-

A smoke-producing stove provided with the grate B, regulated by thegrated dampers d d, and the inner perforated partition-plate D in itsupper part, regulated by a damper or dampers, h h, as described, wherebythe draftand combustion are so regulated as to give out the least heatand the greatest amount of smoke, as required, substantially as hereinspecified.

Specification signed by me this 14th day of March, 1873.
